Why do metals dissolve in acids?

Answer:

In water or acids, the metals trade places with hydrogen. The hydrogen escapes as a gas, and metal atoms, no longer attached to the object from which they came, dissolve in solution.

Electrons are negatively charged. acids are positively charged. when an acid in contact with a metal, the acid steals free electrons away. That loosens the bonds holding metal atoms in place, so the metal dissolves.

Comment on why do you think cells prefer to use carbohydrates as a source of energy before they use fats and proteins.
kompoz [17]

Answer:

This can be explained  based on structure, and on metabolisms of  carbohydrate.

Explanation:

Carbohydrate has a relatively simple structural composition than the  either protein or fatty acids. The C, H and Oxygen molecules are of  relatively fewer in number and few  chains than fats and protein.Thus  cells will spend less energy to break bonds(catabolisims) among these molecules during cellular respiration  pathways  to trap the energy.

In addition glucose the end products of carbohydrate did not need any processing before it enters glycolysis, Kreb's Cycle and oxidative phosphorylation pathways to generate energy for the cells.

Conversely, for protein to be used it has to be first deaminated(removal of amino acid) by the liver  before it enters glycolysis,while fats needs to  be broken down and undergo beta oxidation   with the long chains removed  before it can  form acetyl CoA. Therefore cells will prefer few steps, less endergonic  pathways of glucose than longer more endergonic amino acids  and fatty acid pathways.

Furthermore, glucose can be used in cellular respiration to  produce energy either aerobically or anaerobically, while fats can only be used anaerobically. Therefore, since cells usually prefer to thrive in aerobic conditions they  breakdown glucose easily during this period, and when lack of oxygen occurs they switched to anaerobic, Thus, the versatility of glucose to oxygen concentration makes glucose a better choice. Besides if fats was used anaerobically, ketone bodies build up which may be toxic to the cells.

Polydactyly is an autosomal dominant trait in which affected individuals have more than five fingers and/or toes. If a pedigree
bija089 [108]

Answer:

Reduced penetrance or incomplete penetrance

Explanation:

Penetrance refers to the extend which a certain gene or set of genes is expressed in a population.

It can be complete where there is expression of the gene in a population having it.

Whereas, in reduced penetrance is where the mutation is not expressed in every individual in the population having it.

For instance polydactyly exhibits reduced penetrance since the parents had the mutation it was not expressed it came to be expressed on their pedigree.
